    Default While JOptionPane equal Yes????

    I want the while at the end to say while JOption says yes. Meaning when asked if they want to play again it will re loop and play it again if they click yes. I have looked and I can't find how to do it. I also used an "int" which was selection, but it says i need a boolean value which kinda makes sense but I dont know how..

    Thanks

    package lab3;
     
    // Import
    import java.util.Scanner;
    import javax.swing.JOptionPane;
     
    // Start
    public class Problem4 {
        public static void main (String[] args){
        // It's time to play the lottery!
    int selection;
     
     
         do{ int lottery = (int)(Math.random() * 1000);
     
          int runAgain;
     
     
        // Promt the user to enter a guess
        Scanner input = new Scanner(System.in);
        System.out.println("Enter your lottery pick (three digits): ");
        int guess = input.nextInt();
     
        // Get digits from lottery
        int lotteryDigit1 = lottery / 100;
        int lotteryDigit2 = lottery / 10;
        int lotteryDigit3 = lottery % 10;
     
        // Get digits from guess
        int guessDigit1 = guess / 100;
        int guessDigit2 = guess / 10;
        int guessDigit3 = guess % 10;
     
        System.out.println("The lottery number is " + lottery);
     
        // Check the guess
        if (guess == lottery)
            System.out.println("Exact match: You win $10,000!");
     
     
        else if (guessDigit2 == lotteryDigit1
              && guessDigit1 == lotteryDigit2)
            System.out.println("Match all digits: you win $3,000");
     
     
        else if (guessDigit1 == lotteryDigit1
              || guessDigit1 == lotteryDigit2
              || guessDigit1 == lotteryDigit3

            System.out.println("Match one digit: You win $1,000");
     
     
        else
            System.out.println("Sorry, no match. Try again!");

     "Would you like to run another?","Confirmation",
        JOptionPane.YES_NO_OPTION);}

    The conditional needs a boolean, so you must use a boolean, or in this case compare the two integers using '=='. In addition, the API for JOptionPane explicitly states what is returned for this method based upon the user action.
    while (selection == JOptionPane.YES_OPTION);
